Acohort study was conducted to study the association of coffee drinking and anxiety in a population-based sample of adults. among 10,000 coffee drinkers, 500 developed anxiety. among the 20,000 non-coffee drinkers, 200 cases of anxiety were observed. what is the relative risk of anxiety associated with coffee use?

Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.

Step-by-step explanation:

Since we have given that

Number of coffee drinkers = 10000

Number of whom developed anxiety = 500

Number of non coffee drinkers = 20000

Number of whom developed anxiety = 200

So, probability of getting anxiety from coffee drinkers =

Probability of getting anxiety from non coffee drinkers =

so, Relative risk of anxiety associated with coffee use is given by

Hence, Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.
